Dvorak keyboard mapping?
There is a maintained repo on Github by BioticPixels with a script that does this exactly https://github.com/BioticPixels/Blender-Dvorak-Key-Configuration, (more permanent link). It appears to not be feature complete but the author lists the restrictions and it appears to be usable for the most part. There are install instructions present or you can open your text editor and execute the script from there. Direct link.
